Mixed reaction
Well, a few things about this tutorial. You obviously put some work into this, that shows. But there's a few things holding it back.
First, while the presentation is pretty, there are two things that could be tweaked to make it more efficient.
One is getting rid of your splash screen. People using this as a reference just want to get to the info fast, and that few-second wait before the menu just slows em up.
Issue number Two is that there should be a button leading directly to each section, rather then just having it all on single line. Add to that a button on each page leading back to the main menu. Again, the reason for this would be speed.
Issue number three concerns you dragging code:
on(press){
startdrag("");
}
on(release){
stopDrag();
}
The "on(release)" should read "on(release, releaseOutside)" to get rid of that annoying bug that sometimes crops up where the item dragged doesn't let go of your cursor.
Lastly, I gotta say that while providing code and showing how to implement it is nice, actually showing what the parts of a script mean would be so much better. But yeah, I know that's much harder to do.
Good job for what your we trying to do, though.
